International and European regulations are changing how the maritime industry evaluates fuel. For biofuels, emissions reductions depend on sustainability and traceability, while their compliance value varies across the regulatory frameworks now in effect.
For shipowners and operators, choosing a lower-carbon fuel is only part of the decision. They must also understand how its sustainability credentials are demonstrated and how it can support their wider compliance strategy.
At Peninsula, we see RED III, FuelEU Maritime and the EU Emissions Trading System (EU ETS) bringing lifecycle emissions, sustainability, traceability and regulatory exposure into commercial decision-making. The challenge is to understand what a fuel can deliver within a customer’s specific operational and regulatory context.
Three frameworks, different objectives
The three frameworks are connected, but they place different obligations on different parts of the market.
RED III sets sustainability standards for renewable fuels and introduces an obligation on marine fuel suppliers to deliver a proportion of sustainable fuel into the fuel mix. Because each EU Member State implements the directive through national law and on its own timeline, requirements and compliance costs can vary between markets.
FuelEU Maritime places an obligation on shipowners and operators by progressively reducing the permitted greenhouse gas intensity of energy used on board ships within its scope. It does not prescribe a particular fuel, allowing qualifying biofuels to support compliance when their lifecycle emissions savings are properly evidenced.
EU ETS also places an obligation on shipping companies. They must surrender allowances for emissions covered by the scheme, creating direct financial exposure to carbon emissions. Using eligible lower-emission fuels can reduce that exposure.
A product’s regulatory value therefore depends on its feedstock, lifecycle emissions savings, sustainability evidence and the framework under which it is used, not simply on being described as renewable or lower carbon.
Through our supply activity and customer conversations across markets, we see how differences in RED III implementation can affect availability, compliance costs and procurement decisions. That market visibility helps us assess biofuel options in the context in which they will actually be used.
| Framework | Who it affects | How qualifying biofuels can help |
| RED III | Marine fuel suppliers | Contribute to renewable-fuel obligations when sustainability criteria are met |
| FuelEU Maritime | Shipowners and operators | Lower the greenhouse gas intensity of energy used on board |
| EU ETS | Shipping companies | Reduce covered emissions and associated allowance exposure |
Where biofuels fit
Biofuels offer a practical route to reducing emissions while integrating with existing marine operations. When they meet the relevant sustainability and documentation requirements, they can also support compliance with FuelEU Maritime, EU ETS and renewable-fuel obligations under RED III.
The economics of biofuels are also evolving. While they have often been viewed as carrying a premium to conventional fuels, market movements can narrow, or even reverse, that gap. In Rotterdam, for example, recent B100 pricing moved from a premium to a slight discount against VLSFO once EU ETS and FuelEU Maritime benefits were taken into account. This reinforces the need to assess the complete business case, including the physical fuel price, regulatory benefits, potential penalties and allowance exposure.
Through our market activity and customer conversations, Peninsula helps customers evaluate these variables together, considering the vessel, route, applicable framework and commercial objective rather than relying on assumptions about the cost of biofuels.
Nor do all biofuels deliver the same value. Feedstock, lifecycle emissions savings and certification can all affect how a fuel is recognised under a particular requirement.
Sustainability must be demonstrated
This is why certification and traceability are critical. A sustainability claim needs evidence behind it.
ISCC certification provides an independently verifiable framework for demonstrating sustainability, traceability and greenhouse gas emissions savings across the supply chain, and is widely used to support compliance with RED III.
Traceability extends from the origin of the feedstock through to the customer. Proof of Sustainability documentation records key information as the product moves through the chain, while independent auditing supports the integrity of the process. Peninsula uses this product and documentation expertise to connect certified fuel, traceability and lifecycle emissions data with the requirements relevant to each customer.
Peninsula’s biofuels are derived from second-generation and certified materials and supported by an integrated supply chain spanning cargo, sales, storage, operations, logistics and shipping. This gives us oversight beyond the point of delivery, helping us demonstrate what is being supplied, support the credentials associated with it and identify potential issues across the supply chain.
Compliance is not one-size-fits-all
Navigating biofuels is more complex than switching from one fuel to another because RED III, FuelEU Maritime and EU ETS approach decarbonisation from different perspectives.
In our work with customers, we look beyond whether a biofuel is sustainable to assess where it comes from, how its sustainability has been verified, what documentation accompanies it and how it will be recognised under the framework relevant to the vessel.
These questions matter as operators balance emissions reduction with operational requirements and the economics of compliance.
This is where Peninsula adds value. We bring together compliant, traceable and high-quality sustainable fuel solutions with market insight, documentation expertise and a reliable, scalable supply chain. Rather than treating biofuel as a standard product, we consider the vessel, route, applicable framework and commercial objective to identify the most appropriate solution.
Turning regulation into practical decisions
Regulation adds another dimension to marine energy procurement. Peninsula supports customers through that complexity by bringing together the physical product, its sustainability credentials, supply-chain capability and an understanding of where and how it will be used.
Our objective is not simply to supply biofuel. It is to help customers understand the practical considerations around the product and select solutions suited to their operational, commercial and compliance requirements.
With biofuels, compliance is about more than the fuel itself. It depends on where the fuel comes from, how its sustainability is demonstrated, how it is used and the regulatory framework under which its value is recognised.
